Abstract
Formal translation directed by parallel LLP parsing is presented here. The translator follows the traditional translation scheme – the input grammar is extended by output symbols that are added into appropriate right-hand sides of grammar rules. The translation algorithm is based on the intermediate results provided by the parallel LLP parser. The correct sequence of output symbols is obtained from the intermediate results using the parallel prefix sum, the segmented parallel prefix sum, and parallel sorting steps. The translation algorithm presented here is suitable for all translations with LLP(q,k) input grammars. The asymptotical parallel time of the translation algorithm is \({\mathcal O}(\log^2(n))\).
